This diagram from a 1967 documentation shows how to switch high voltage neon lamps with 5V TTL outputs. The circuit can be adapted to function as a shield.
This 80's Motorola circuit can generate 100 MHz signals, but they can reach 200 MHz with the...
Of course, the current is extremely small, but a voltage of 300 V can be obtained from 9 V of a...
We found this solid-state relay circuit that can function as a shield in a Radio Electronics...
